POULTRY CERTIFICATION INCREASES 



Diu'ing the season of 19"37-':;8 a system of poultry certification was begun, 

 and appro.ximately S'^.STO birds were handled for certification bv H. O. 

 Stuart. Only accredited flocks are given certification. The ijurj^ose of the 

 work is to sejiarate the hens into three classes depending on their ability 

 to ])roduce chicks having the qualities needed for high ^^i:^ ])roduction. 



The first is the breeding class and contains all the birds that .show satis- 

 factory production qualities and are free from an.y inferior qualities which 

 might be inherited. The second class contains birds suitable only for e^g 

 production. They may be oflf-type in color from the rest of the flock, off- 

 color ear lobes, have side sprigs, feathers on shanks, have a comb foreign 

 to the breed, or have ''down" on their shanks or toes. Any one of these 

 defects makes a bird undesirable for breeding stock. The third class is 

 made up of culls unfit for economical egg production or breeding stock. 



About 3,435 birds were also handled in selecting breeding stock from 

 non-accredited flocks. (Miscellaneous Income.)
